Running Containers as Root User Should be Avoided

Description:

Containers shouldn't run as root users in your Kubernetes cluster. Running a process as the root user inside a container runs it as root on the host. If there's a compromise, an attacker has root in the container, and any misconfigurations become easier to exploit.

Solution: 

1. From the Unhealthy resources tab, select the cluster. Security Center lists the pods running containers missing the 'MustRunAsNonRoot' rule.
2. For these pods, add rule: 'MustRunAsNonRoot' in a runAsUser section of the container's spec.
3. After making your changes, redeploy the pod with the updated rule.
